Passat (B5) :: Loud High Pitch Noise From The Motor On Cold Start Up
Sep 21, 2011
Every morning for the last 3 days I've gone to go warm up my car and each time i turn on the car only from a cold start up i hear this loud high pitch noise from the motor. If i turn the car off and restart it. It goes away and the car is at perfect idle. what is this and do i have some serious problems?
Is this true? If it's only on a cold start up, and then it goes away during normal driving, you have no need to fear....that's the Secondary Air Injection Pump that turns on during cold starts, and the plastic hose just needs to be replaced.. If so where is it located so i can replace this hose.

2002 Passat wagon. I recently had my independent VW shop install new front and rear brake pads and rotors that I provided. The pads are PBR Axis Deluxe ceramic pads. Soon after, the front brakes started a high pitch squeal - mostly when cold or wet.
I took it back to the mechanic and he told me there is nothing he can do about it - I must have defective pads and that maybe they are covered under warranty, as they certainly need to be replaced, ...
This shocked me, especially the lack of customer service, but because I provided the pads I don't think I have much leverage with them other than not to do business with them again.
Is there any way to quiet a squeaking brake pad? Might the mechanic not done something he should have done to prevent squeaks?

I bought a 1995 k2500 sheyenne. There is a rather loud high pitch grinding/ squeaking noise emitting from what I would say the rear right of the truck. I have completely replaced the brake shoes and new pins and springs. No luck. What I can say is:
1. It hardly gets any louder as I speed up.
2. Still screams when in neutral, as long as the truck is rolling.
3. Rear differential has plenty of fresh fluid when I bought it.
4. If i hit a good size bump, it will run quiet for about 15 seconds.

I replaced the timing belt an waterpump at 262,000 miles and ever since the engine makes a loud low pitch noise that varies in pitch depending on the engine speed. I replaced the alternator and it didn't work. I don't know if the power steering pump, a/c compressor or something else is making this awful sound.

I've got a 2004 1.8T 4motion passat and when it starts cold in the morning it makes a loud noise for a minute or so then it stops and is normal again, I'vev been told by a local autoparts store that it is possibly the auxiliary/secondary air pump that needs to be changed to fix this poblem. if it is the air pump how hard is it to change and do u need any special tooling to do it or is it fairly straight forward to change?

There is a loud ticking noise coming from an undetermined location in the engine compartment (sounds more like behind the motor). It starts on cold-start, lasts approximately a minute or so until the engine heats up. Driveability doesn't seem to be affected, and the engine doesn't have any additional weird symptoms. Some other VW owners have suggested changing the cam belt and tensioner to fix this problem, but the car has only just turned 45K miles and can't imagine that it would fail so quickly.

New 2012 SE, I noticed a high pitch noise coming from the rear side of my car. The high pitched noise/whine happens as soon as the car is running, and continues until it is turned off. I can hear it every time when standing idle or at lower speed. So I brought it into the VW dealership, and my technician: "found noise described is the high pressure pump in the tank".
We tested another 2012 Passat SE and we found the exactly same(even louder) high pitched noise coming out from the high pressure pump. I was told by a service manager that it is a standard high pressure pump noise for 2012 Passat. Well I don't think that any high pitch ultra whine/noise should be a standard feature in any car...It is very,very annoying noise...

I lost boost, went from being chipped at 16psi to 7-8 with a check engine code and a high pitch noise. Now is the secondary air pump connected to the turbo in any way. It just happened and I'm working on getting the code read. Just curious if my pump is just bad, what im figuring.

03 focus SE Wagon, Automatic Tran, has a bit of a problem. Whenever it gets driven through a puddle (big, small, paddling pool, etc.) it will make this high pitch squealing noise, and then when it gets shut off after driving through said puddle, will have trouble starting. (It will turn over, catch, run for .2 seconds & then the engine will cut out, but all the electronics will work) THEN! if you can get it started, it needs to be reeved constantly or it will stall when it idles. Lastly, if the conditions are ridiculously horrible, & you need to go some place, you have to '2 foot drive' the little beauty to whereever you're going. Now, she's been in to see the Ford mechanics and has 'stumped' them.

I have 1,600 miles on my elantra and this sound just started. On initial starting, when the engine is cold, there's this loud low pitch then high pitch sound. It only lasts for 1.5 seconds but it's loud. What could it be?

I have a 06 accent sedan and I have been having some issues with the back brakes that were just replaced prior to the motor vehicle being done the end of June. I had the brakes replaced and everything was working fine up until the middle of last week; now the brakes in the back are squealing like the warning plates are rubbing together again (loud high pitch squealing) what could be causing this...I took it back to where I had the brakes replaced and they did a check and said that it did not look like anything was wrong and they asked me when my front brakes were replaced, I told him they were replaced last August when I have a issues with a caliper freezing up and had to replace everything in the front (brakes, caliper etc). So long story short he said to keep driving and see if you can tell if the squealing is coming from the front or the back and come back when its happening or if you can determine which one it is..

Yesterday my truck started making a loud high pitch squeal at idle. Messing with it this morning I found when I turn the a/c on it quits. Then it will do it for a second at startup and quit. If the a/c system is turned off it comes back. I thought exhaust leak until I found the a/c link.

I have a 2000 VW Passat 1.8T Automatic. During a cold start, I notice a rather loud noise like a motor whirring that lasts for approximately 30 seconds. My RPMs also run about 200 higher than idle during this time. After the 30 secs the noise goes away (sounds like this motor powers down) and the RPMs return to normal.
It doesn't happen every time I start the car, just when it has been sitting for more than 4-5 hours or overnight. What this is and what if anything I should do?

My girlfriend has a 2001 Ford Escape 3L, 6cyl. When accelerating there is a loud high pitch whistle/whirling sound. The sound varies with the amount of throttle you give it. More throttle = louder whine. Doesn't seem to do it when idling or coasting. What that could be? I'm about to remove the belt and take a look at the drive belt tensioner and other pulleys.
Just checked pulleys and tensioner and the tensioner seems fine, a/c pulley spins smooth and free no play, alternator spins smooth no play. The belt needs to be replaced. I wouldn't think this would cause such a load whistle under acceleration. I would expect it to do it all the time if it was the belt. I'm looking at the water pump pulley and belt too and they seem ok as well.

Check out how loud my cold start idle is. Still can't figure out why you can't hear the turbo on start up though. Even revving at idle you can't hear it that much. I've seen plenty of gti's with more exhaust restriction then i have and you can hear it clearly. [URL] .....

I have a 1995 Lexus ES300 with 130,000 miles on it. When I reverse, I get a low-pitch growling and as as soon as I apply the brakes by a high-pitch, ungodly screech. This noise is definitely coming from the rear wheel areas. I'm not sure which tire is the culprit (I hear both sides from while listening from both the inside and outside). It happens frequently but is particularly bad on rainy, snowy, misty, or high humidity days. Two years ago I replaced the pads and rotors. At this point, the pads look to have about 40% life on them yet. This problem started happening about a year ago.
My initial thoughts were that it was just rusting because of the frequency on high moisture days. But both noises are way too loud for that. My second speculation was that the emergency brake was catching, but after examining it I think not. I've taken the entire assembly (brakes, rotors calipers, and emergency brake) at each tire apart and looked for any obvious issues that look incorrect. No luck. I've also applied brake quiet with similar results. Now my thoughts are that the low pitch is the rotors being warped. But that doesn't explain the screech and why it only occurs in reverse.

So now that it is winter, I have started to use the heater in the car. It works fine for about 10 minutes until a loud high pitched noise starts. Sounds like something is grinding. Any clue what it is? Is so, how to fix it?

So i have a '06 2.0t 6spdman passat. I started getting this high pitch sound (like a boost leak) when under hard acceleration from second gear and up. I went to the dealer today and they replaced my PCV system, and told me that was the noise i was hearing. Pulled out of the dealer like half a block and same thing happened. Then the tech went with me heard the noise, went back put it on a lift. And proceeded to just rev the engine. They say its my Intake system, yet I have had it on the car for 2 and a half years. Could it possibly be the DV???

I have a 2002 Corolla with about 180,000 miles that has been well maintained, but I know very little about cars.
Over the past months, I've noticed the engine noise on acceleration sounds a bit louder than I would expect it to, and it seems to be getting louder over time. It's slow changing, so I'm a little unsure. And occasionally I wonder if I don't hear a sound that shouldn't be there, though I couldn't describe it yet. Mechanic said the acceleration noise is normal at start-up for older cars until they get warm, but this happens even after I've been driving a while. Worth the $100 for an engine checkup?
Also, the A/C doesn't seem to be the strongest and has a high pitch noise when I run it. Normal?

I'm on my 4th passat. Have an 08 Komfort. This by far is my most favorite of the 4 passats I've owned. This is the first VW I have had with satellite radio. I noticed not long after I got it that I could hear a high pitched beep that lasted maybe 3 or 4 seconds while I was listening to the satellite radio. It seemed to just happen at random times. I took it on a 500 mile trip a few weeks ago and I just figured out exactly when this happens............it happens when I hit the brakes while I am listening to sirius only. It doesn't happen while listening to FM or AM (I didn't try a CD). It doesn't do it every time, but at least 50% of the time. It almost always seems to happen if I have the cruise control on and I hit the brakes to disable it. I'm going to mention it to the dealer when I take it in for service.
